ATOMIZER.

To all whom. it may concern).

Be it known that I, THOMAS J. HOLMES,

a citizen of the United States, residing at Everett, in the county ofMiddlesex and State of Massachusetts, have invented Improvements inAtomizers, of which the following is a specification, reference beinghad to the accompanying drawings, forming part thereof.

This invention has r ference to improvements in atomizers and relatesmore particularly to the construction of the atomizer nozlzle and themembers cooperating there- Wit 1.

One object of the invention is to provide a cast metal nozzle having anoutlet orifice and a surrounding hood or wall, a member of which nozzlehas means to receive a tube supporting member of more durable materialthan said nozzle member.

Another object of the invention is to improve the construction of theatomizer with reference to .the atomizing elements and the return forthe surplus liquid.

Other objects of the invention will appear from the followingdescription.

The invention consists in the improved atomizer having the nozzleintegral with the hood.

The invention also consists in the nozzle member having the novel tubesupporting member.

The invention also consists m such other novel features of constructionand combination of parts as shall hereinafter be more fully describedand pointed out in the claims.

Figure 1, represents a side view of the improved atomizer mounted on abottle or container for liquid to be atomized and having its air tubeprovided with a pressure bulb of well known construction.

Fig. 2, represents an enlarged sectional view as taken on line 2-2 Fig.6.

Fig. 3, represents a similar view with the liquid supply tube and itsholder removed.

Fig. 4, represents a cross sectional view taken, on line 4-4 Fig. 2.

Fig. '5, represents a similar view taken on line 5-5 Fig. 2. 4

Fig. 6, is a similar view taken online 6-6 Fig. 2. v

Fig. 7, represents an enlarged view of the tube holder with a p01 tionof the liquid supply tube.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed April 9, 1917. Serial No. 160,590.

Similar characters of reference designate corresponding partsthroughout.

In carrying this invention into practice I construct, preferably bycasting, an atomizer head having its skirt, atomizer chamber and hoodintegral whereby soldered, brazed or other joints are'avoided. Thearticle as a whole has a better appearance and the cost of manufactureis considerably reduced. I also find that the improved constructionenables me to produce a more durable article particularly as regards thenozzle member which being integral with the skirt or other attaching orsecuring element cannot become loosened from repeated removals orreplacements of the liquid supply tube and its nozzle or because of therepeated cleaning of the nozzle air chamber and its outlet.

As shown in the drawings A represents a bottle r receptacle of anydesired shape and size to contain liquid to be atomized or projected bythe present device. This bottle A has the neck B screw threaded toreceive the interiorly screw threaded skirt 9 of the improved atomizerwhich skirt -9 is integral with the shoulder 10, having the annularpacking receiving channel 11, and with the hood 12 having the outletopening 13. Annular channel 11 embraces the hub or projection 14 whichhas the depression 15 considerably larger than its axially disposedscrew threaded bore 16 which extends to the air chamber 17 located inthe conical member 18 and having the air-supply passage 19 and theoutlet 20. Partially embracing the hub 14 is the curved return passage21 which may be of any shape or size which will not unduly reduce andthereby weaken the integral connection of said hub 14 and shoulder 10.

In the screw threaded bore 16 of hub 14 is removably screwed the tubesupportin member 22 which may be of harder meta than said hub and hasthe flange shoulder 23, and the axially disposed passage 24 terminatingin the nozzle 25 which extends into air chamber 17. Shoulder 23 fitsdepression 15 of hub 14 and has a considerable area bearing against thewall of said depression so that flange shoulder 23 forms a stop toprevent the undue screwing inward of member 22. In this member 22 issecured the liquid supply tube 26 which extends into Said bottle A.

. 'ecured to one side of hood 12 is the air supply pipe 27 whichcommunicates with the I air supply passage 19. Usually air under more orless pressure will be supplied to said pipe 27 by means of the usualcompression bulb 0 attached to said pipe.

In the preferred manner of constructing this device a casting is madehaving the skirt 9, shoulder 10 and hood 12 with its integral member 14:having the depression 15, the passage 16, the air chamber 17 and thereturn passage 21. An air inlet is formed through the wall to airchamber 17 and passage 16 is furnished with a screw thread. At sometimein the finishing process the article is placed in a lathe andits-exterior is turned down, trued and finished, and finally plated ifdesired. The parts 22, 26 and 27 are then secured in place.

By this improved construction I am able to produce the main part of thearticle from white metal so called, preferably making the part 22 ofbrass.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

said hood, said member having also an air chamber having liquid and airinlets and an outlet, a liquid supply pipe having a screw nozzle screwedin said liquid inlet and having an enlarged shoulder seated against saidmember, and an air supply pipe fixed on the exterior of said skirt andcommunicating with said air inlet.
